A sterile device made of alloplastic materials [e.g., titanium (Ti), stainless steel, ceramic] intended to be surgically implanted into alveolar and/or basal bone of the mandible or maxilla to provide support and a means of retention for a dental prosthesis (e.g., bridge, single-tooth, overdenture). It is a two-piece device composed of an anchorage component (implant body) in the form of a threaded screw that is implanted into bone, and a retention component (implant abutment), typically attached to the anchorage component after implantation, that protrudes through gingival tissues to support the prosthesis.
